I visited a shop (with no CCTV) in a society complex in Indirapuram, Ghaziabad and the guy printed some document for me and I forgot my pen drive there, at the same time, he forgot to give it back to me. The next day I visited the shop to collect it back, he casually denied me of any pen drive there. Not sure, if he has lost it or doesn't want to give it back to me. The guy was rude definitely. The pen drive contained a few pieces of digital artwork created by me. I want to know, what are my rights to get it back, and what should be the approach legally?
